Answer:
(3, -2)
Step-by-step explanation:
both of the equations are equal to y, which means they are equal to each other.
So you write them as equation(1) = equation(2)
and solve for x.
Next substitute the value of x to any of the equations and find y. And that is how I got (3 , -2)
Hope I was able to help:)
Answer:
-23.99048X + 310.7619
Step-by-step explanation:
Given the following :
Time(weeks) - - - mass(grams)
0 - - - - - - - - - - - - - 400
3 - - - - - - - - - - - - - 201
6 - - - - - - - - - - - - - 98
9 - - - - - - - - - - - - - 50
12 - - - - - - - - - - - - 24
15 - - - - - - - - - - - - 12
Using the regression calculator, the model for Mass(time), which best fits the data is represented by the equation:
ŷ = -23.99048X + 310.7619
Where, - 23.99044 is the slope or gradient
X is the time(t)
y is the Mass
310.7619 is the intercept. Point where the graph crosses the y-axis.
Hi dear i will tell the first question is b but i did not know it will be correct or no .
<u>Solution-</u>
The given equation,
Then, we have to calculate two points that satisfy the equation,
Calculating y for x = 0,
So, point (0, 4) satisfies the equation.
Calculating y for x = 1,
So, point (1, -9) satisfies the equation.
Plotting the graph taking this two points, as shown in the attachment.
Location is the position of places and people on earth. Location can be described into two ways which is absolute and relative location. Absolute location is not anything more than a simple point regularly recognized on a grid of the surface of the earth named a coordinate. Latitude and longitude can be used to identify a location. The absolute location of new orleans is 30 degrees north and 90 degrees west. However, relative location is the correlation of a place to other places. New orleans is situated at the place somewhere the mississippi river clears into the gulf of mexico which provides it easy right of entry to ocean and river shipping.
